# Goldman Sachs > Goldman Sachs is a leading global money-center investment bank whose public developer surface is institutional and professional-client oriented. It spans the Marquee digital platform (content, pricing & risk, hedging, indices, portfolio and market-data services plus the open-source GS Quant Python toolkit), the Transaction Banking (TxB) embedded-banking APIs for virtual accounts, payments and reporting across Fedwire/ACH/SWIFT rails, and the RIA Custody (GS Custody Solutions) REST APIs for advisor firms.
